Patch 8.2.3268
Problem: Cannot use a block with :autocmd like with :command.
Solution: Add support for a {} block after :autocmd. (closes #8620)

script. Thus this depends on where the autocmd is defined, not where it is
triggered.
+ {cmd} can use a block, like with `:command`, see |:command-repl|. Example: >
+ au BufReadPost *.xml {
+ setlocal matchpairs+=<:>
+ /<start
+ }
+
Note: The ":autocmd" command can only be followed by another command when the
'|' appears before {cmd}. This works: >
:augroup mine | au! BufRead | augroup END

The {repl} argument is normally one long string, possibly with "|" separated
commands. A special case is when the argument is "{", then the following
lines, up to a line starting with "}" are used and |Vim9| syntax applies.
